Appliceiion filed-October 23, 1912. Serial No. 727,301-

All this is usual and standard construction and only necessarily considered in connection with the guard which I will now describe. This guard consists of a bent top bar to which I shallrefer generally as 10, co held in place by a forward; downwardly bent end 8 and a rear, downwardly bent end 9. These ends 8 and 9 serve 'to hold the bar in proper position across theislot 5 being driven Into the iv oool of the shuimlo or body 1 to holdthe bar'in properfrelotion loonlng or like sections during the run of thereto.

The portions 10 and. 10 preferably erarelished motive which the operator is cross the slot 5 at right angles go as to form accustomed to ma re in threading: the most efi'ective bars to direct unthreading I accomplish my object by forming a Inovement n the line of the slot. The porilh guard shaped overlie e portion of ihe t1 on 10 Is also preferably disposed at about 8 hreardingelot and so formed as to guide the right angles to the eye 4 and substantially thread in such 2: Why that, although apglied parallel with that portion of the slot 5 Which to the outside of? the guard it will transfer enters the bobbin chamber 2.

Any deings by like numerals correspondingly used threading motion is therefore opposed by throughout. the pal-[3'9 or 10-" or if the thread should at Ta-eEwMm it may eo'ncem Be it known that I, Enannn H. DAUDELIN, a citizen of the Unitedfitetcs, residing at, Fall River, county. of" Bristol, Commonwealth of Meseochusetis have invented certain new end. useful Improvements in 'fihuttles, of w 'iich the following is a specification.

This invention relates to'haind threading shutties and particularly to the guarding of PM)? the threading slot or passage to prevent the escape or" the thread from the slo', by bad-- Figure- 1 a plan View of the threading tempt to Work forwnrdin the slot 5 itwould end of e shuttle equipped with my im enk lneot ithe transversely lisposedp art 10 tion Big. a central longitudinal seca The portion 10" of the guard has been detion of the parts shown in land Fig. scribcd as raised ahovethe levels of the portions 10 and 10?. In the threudingppera- 3 is a View of thevguard removed. 50 The shuttle body 1 may oi'imy usual eonctrlnraion having c bobbin Cllfllllbfil QLlIl i (referring to the parts as disposed in Figi w ich is located the ihobhinifi on which 1) and drawn down so thutgpossinghnder Woend a thread T. From on oriverd end the portions 10?, 10* and 10 it entersethe slot I 5 at the edgeof the shuttle and lands at the intersection of the slots 5 and 6-. At this 119 of the bobbin cl'uimhr 2 leads the eve to which the threading 5 and 8 conneoi ion the thread 1 is passed above thehar 10- onenext made with my invention, is a rear- Ward pull. Its effect is as followsz The slight backward movement of the hand causes the thread '1, while being pulled through theslots 5. and G to travel back on claims.

the bar 10 across which it isbeing drawn. This baekwardmovement will land it instantly on the-portion 10' from which it successively slips to 10 thence to 10* until it pullscpast 10 During this movement it has been passing substantially, vertically down through-the slot 5 and all the time slipping back toward the direct connection between the eye 4 and the bobbin chamber 2. As soon as it passes the portion 10 it is landed between the vertical part 9 and the pin 11 and at the same time its outer end is laid within the eye 4.- through which it may eed.

Any unthreading tendency which may originate withinthe bobbin chamber is met with the transversely disposed parts 9 or 10 which absolutely bar the way.

Any move back from the opposite end of the slot is squarely met by the transversely disposed part 10".

It will readily be seen that as far as the slot is concerned the thread is absolutely barred at either end from voluntary movement.

Various modifications in the bending of the guard, in the material and construction thereof, in the exact disposal of the same and generally in the details of form and arrangement may absolutely be made, all without departing from the spirit of my invention if within the limits of the appended What I therefore claim and desire to secure by Letters Patent is:

1. In a shuttle of the class described, having a transverse delivery eye and a threading passage with an exposed upper edge and an oppositely extending underlying portion, a threading bar disposed across said exposed edge and extending from the delivery side of the receiving end of thethreading passage at the rear of the delivery eye to the opposite side of said passage forward of said eye. 2. In a shuttle of the class described having a delivery eye and a threading passage leading thereto, a thread guide set transversely to the plane of entry of the thread into said passage and adapted to form a loop in said thread during said entry, said guide having surfaces having a directive tendency toward said delivery eye;

3. A guard for. the threading slot of a shuttle consisting of a bar, means for supporting it transversely of the slot, said bar comprising a central bowed poition and substantially straight portions connecting the ends of said bar with said supporting means, said bowed portion being slightly tilted. up.

4. In combination with a shuttle of the class described, a guard for the threading slot, comprising anoverlapping section having a rearwardly inclined guiding edge on one side and transversely disposed. barring edges on. the opposite side.

5. In combination with a shuttle of the 'class described a transverse guard for the threading slot thereof consisting of a bar having downturned ends'lodged in the shuttle, said bar having a central bowed portion overlying, said slot in general parallelism therewith.

6. In a shuttle of the class described having a threaded slot a bar running from the throat at one side of the slot overlying a portion of said slot between its ends, returning to the side of the slot fiist mentioned and again traversing said. slot.

7. In a shuttle of the class described a guard for the threading slot comprising a bar disposed transversely thereof adjacent to the shuttle edge and. extending rearwardly adjacent to said slot.

8. In a shuttle of the class described. having a threading slot, a thread guide disposed across said slot but adjacent thereto and adapted to hold a loop of the thread during the passage of the thread through said slot.

In testimony whereof I aii ix my signature in presence of two witnesses.
